THOMAS BARBER, OF FLATBUSH, NEW YORK.

STEAM-CONDENSER.

.SPEGIFICATION forming part of Letters Patent No. 320,746, dated June23, 1885.

Application filed January 29, 1885.

To all whom, it may concern:

Be it known that I, THOMAS BARBER, a citizen of the United States,residing at Flatbush, in the county of Kings and State of New York, haveinvented new and useful Improvements in StcamCondensers, of which thefollowing is a specification.

The invention consists in a steam-condenser composed of condensing andcold-water pipes constructed and arranged as hereinafter described andclaimed, and also in a condenser consisting of acondensing-pipe whichreceives the exhaust steam at one end, while the other end is adapted tobe connected with the suc' tion-pump, a cold-water pipe which partiallysurrounds said condensing-pipe and opens into the same near itsreceiving end, a valve situated in the cold-water pipe, and a slot orslots formed in said valve.

In the accompanying drawings, Figure 1 represents a longitudinalvertical section in the plane 3 3/, Fig. 3, of my improved condenser.Fig. 2 is a vertical section of the same in the plane y y, Fig. 3. Fig.3 is a horizontal transverse section in the plane 00 m, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the condensing-pipe, which isprovided with a conical receiving end, a, which end is adapted to beconnected with the engine in a suitable manner to receive the exhauststeam thereof. The other end, b, of the condensing-pipe A is providedwith a turn, and is adapted to be connected with a suitablesuction-pump.

B is the cold-water pipe, which partially surrounds the condensing-pipeA and opens into the same near its receiving end. Before opening intothe condensing-pipe A the coldwater pipe forms an approximatesemicircular bend, c, in order that it may open into the condensing-pipeat about a right angle. The exhaust-steam from the engine passes alongthe condensing-pipe A in the direction of the arrows shown in said pipe,and is met at the point where the cold-water pipe opens into the saidpipe by the cold inj ectionwater forced or drawn through the cold-waterpipe B in the direction of the arrows shownin said pipe. The water ofcondensation, together with the water injected, then passes down thepipe A and out of the condenser, and, since the said (No model.)

condcnsingpipe is partially surrounded by the cold-water pipe, any steamwhich was not condensed by the spray will be condensed by coming intocontact with the cold walls of the condensingpipe.

In order to regulate the supply of water, I place a valve, (J, in thecold-water pipe B at or near the junction of said pipe with thecondensing-pipe A. This valve 0 is mounted on a shaft, (2, one end ofwhich extends through the walls of the cold water pipe, passing througha suitable stufiing-box, I), and the other end has suitablebearings,c,in the opposite wall.

011 the end of the shaft which extends through the walls of thecold-water pipe is secured a ratchet-wheel, f, which is engaged by apawl, g, swung from a pivot, h, secured to the cold water pipe, and onthis same end is secured a handle orlever, t, for turning the shaft. Theteeth of the ratchetwheel face in such adirection that when the handleis turned the valve will be held in any desiredposition. In order toobtain a good distribution of the water, the valve is provided with aslot or slots, j, extend ing across the same.

By arranging condensing and cold-water pipes as above described acondenser is obtained which acts to a certain extent as aninjection-condenser and a surface-condenser, the result being that lessinjection-water is required for the condensation of the exhaust, and atthe same time the construction is very simple, as the cold-water andcondensing pipe can be cast integral, as shown in the drawings.

WVhat I claim as new, and desire tosecure by Letters Patent, is-

l. A StGZtDI'COIIClGHSGI consisting of a condensing-pipe, A, having anopen end, a, for connecting with an engine, and provided at its otherend with a lateral bend, b, for connecting with a suction-pump, and acold-water pipe partially surrounding the condensingpipe and having anapproximately semicircular bend, 0, so that the cold-water pipe opensinto the condensing-pipe laterally at or near right angles thereto,substantially as described.

2. A stealn-condenser consisting of a con- (lensing-pipe, A, having oneend, a, for connecting with an engine, and the other end, Z),

for connecting with a suction-pump, a cold- Water pipe partiallysurrounding the condensing-pipe and opening thereinto at or near rightangles thereto, and a pivoted swinging valve, 0, arranged at the pointof communication between the condensing and cold-water pipes forcontrolling the distribution of Water into the condensingpipe,substantially as described.

3. A steam-condenser consisting of a condensing-pipe, A, which receivesthe exhaust steam at one end, while its other end is adapted to beconnected with the sucti0n-pu1np, a coldwater pipe, B, which partiallysurrounds said condensing-pipe and opens into the same near 15 itsreceiving end, a valve, 0, situated in the cold-water pipe, and a slotor slots formed in said valve, substantially as and for the purposedescribed.

In testimony whereof I havehereunto set my 20 hand and seal in thepresence of two subscribing witnesses.
